Definitions
- This invention relates generally to applications that are declarative (passive) content, executable (active) content, or some combination of declarative and executable content.
- a cascadable state machine for broadcast content that includes a collection of rules for how content objects that control other pieces of content would reflect their execution states is disclosed.
- the javax.tv.xlet.Xlet interface provides
- a cascadable state machine that observes the execution state
- a method for providing a cascadable state machine is
- execution state machine interface as the client applications, and cascading a change to
- computing system arranged to provide a cascadable state machine in a computing system
- Fig. 1 illustrates a platform that receives an application that has both declarative

- Fig. 9 illustrates a computer system employed to implement the invention.
- a cascadable state machine that observes the execution state
- Fig. 1 illustrates a platform 100 that receives an application that has both
- declarative (passive) content and executable (active) content.
- executable (active) content The declarative content
- the application and the platform conform to interoperable interfaces.
- the application adopts
- execution state machine and exports a standard, interoperable interface through which
- FIG. 2A An execution state machine 200 for broadcast content that executes on interoperable platforms is shown in Figs. 2A and 2B.
- the execution state machine 200 consists of four states, i.e., loaded (L), paused (P), deleted (D), and resumed (R).
- Fig. 2A illustrates the operations that the platform can perform on the application.
- the application exports a standard interface through which the platform causes execution state transitions.
- Fig. 2B illustrates the operations that the application can perform on the platform.
- the platform exports a standard interface through which the application reports execution state transitions.
- the role of the executable content is to parse and render the declarative content.
- the platform exports standard, interoperable interfaces to which the application can delegate these operations.
- the executable content consumes both broadcast bandwidth and platform footprint.
- Fig. 3 illustrates an additional architecture 300 in accordance with an embodiment of the invention.
- the architecture 300 amortizes the executable content across the declarative content of multiple applications. Since the platform must manage the content, the applications also include just enough executable content to implement the execution state machine.
- three applications export the standard, interoperable execution state machine interface, but delegate execution intensive operations to a common collection of downloadable packages. The advantage is that the platform provides resident packages to support a small (perhaps zero) collection of pervasive content formats, but the cooperative applications can share downloadable
- Fig. 4 illustrates the situation where the application packages and the delegate packages both adopt the standard execution state machine and for the application packages and delegate packages to both export the standard execution state machine
- the delegate package exports the standard execution interface to the platform, but the delegate package also observes execution state transitions of the client
- the delegate package reflects the execution state transitions of its clients
- the design provides precise rules about the interaction of the client execution states versus delegate execution states. The implication is that the platform
- Fig. 5 illustrates a variation on the architecture in which the applications export
- the delegate rather than the platform.
- the delegate in turn exports the standard interface
- the architecture requires precise rules for the propagation of
- Fig. 6 shows a Table 1 that characterizes the situation where the delegate
- the table rows encode the execution state before a state transition while the table columns encode the execution state after a state transition.
- the character encodes the state that the delegate reports after the client state
- Fig. 7 shows a Table 2 that corresponds to the situation where the delegate
- the table cells with a character represent feasible client state transitions.
- Fig. 8 shows a Table 3 that corresponds to the situation where the delegate supports three client applications, or the delegate supports multiple client applications
- the table cells with a character represent feasible client state transitions.
- One implementation of the logic would be a dispatch table.
- the client state transition For example, if the client transition is vahd but does not cause
- the delegate reports (or requests) the
- delegate code returns to the client without an exception. If the operation returns an exception, the delegate code perhaps cascades the exception to the client. If the client
- the invention provides an apparatus that observes the execution state
- FIG. 9 illustrates a computer system 1100 employed to implement the invention.
- the computer system 1100 or, more specifically, CPUs 1102, may be arranged to
- ROM acts to transfer data and instructions uni-directionally to the
- CPUs 1102 while RAM is used typically to transfer data and instructions in a bi- directional manner.
- CPUs 1102 may generally include any number of processors. Both
- primary storage devices 1104, 1106 may include any suitable computer-readable media.
- the mass memory device 1108 is a computer-readable medium that may be used to store instructions.
- mass memory device typically stores programs including computer code, data, and the like.
- 1108 is a storage medium such as a hard disk or a tape which generally slower than
- Mass memory storage device 1108 may take the
- mass memory device 1108 may, in appropriate cases, be incorporated in standard fashion as part of RAM 1106 as virtual
- a specific primary storage device 1104 such as a CD-ROM may also pass data uni-directionally to the CPUs 1102.
- CPUs 1102 are also coupled to one or more input/output devices 1110 that may
